Wuxi Yansheng Technology Co., Ltd. has been a trusted manufacturer of high-quality copper tubing since 2017, with a factory spanning over 1,000 square meters and an annual export value exceeding US$50 million. Our Anti-Corrosion C12200 Seamless Copper Coil Tube is engineered specifically for air conditioning and refrigeration applications, offering superior corrosion resistance and excellent thermal conductivity. This pancake coil raw material is the ideal choice for manufacturers seeking reliable, long-lasting performance in their HVAC systems.
Let’s dive into the detailed features and benefits that make our C12200 copper coil stand out in the market.
Product Features & Technical Specifications
Material Excellence: Made from C12200 phosphorus deoxidized copper (DHP), which provides exceptional resistance to corrosion and oxidation, even in harsh environments.
Seamless Construction: Each tube is manufactured through a seamless extrusion process, ensuring uniform wall thickness and no weak points. This eliminates the risk of leakage under high pressure.
Pancake Coil Design: The coil is wound into a flat, compact “pancake” shape, making it easy to transport, store, and handle during installation or further processing.
Thermal Conductivity: Copper’s inherent thermal properties ensure efficient heat transfer, directly improving the energy efficiency of air conditioning units.
Anti-Corrosion Treatment: The tube surface is clean and free from burrs, with an optional anti-corrosion coating available upon request to extend service life in coastal or industrial areas.
Customizable Dimensions: Outer diameters from 3/8” to 5/8”, wall thicknesses from 0.6mm to 1.5mm, and coil lengths tailored to your production needs.
Key Parameters (Typical Values)
| Parameter | Value |
|---|---|
| Grade | C12200 (DHP) |
| Tensile Strength (Annealed) | ≥ 200 MPa |
| Elongation (Annealed) | ≥ 40% |
| Purity | 99.90% minimum copper content |
| Working Pressure (Typical) | Up to 4 MPa (depending on wall thickness) |

Customer Benefits
Reduced Maintenance: The anti-corrosion properties minimize pitting and scaling, lowering the frequency of system repairs and replacements.
Easy Installation: The pancake coil can be easily unrolled and cut to the required length, saving time during assembly.
Consistent Quality: Each coil undergoes rigorous testing for dimensions, surface quality, and pressure integrity to ensure batch-to-batch consistency.
Cost Efficiency: Longer coils (up to 50m per roll) reduce waste and splicing, optimizing your production yield.

FAQ – Frequently Asked Questions
What is the difference between C12200 and C11000 copper? C12200 is phosphorus deoxidized copper with enhanced corrosion resistance, making it more suitable for air conditioning systems where moisture and chemicals may be present. C11000 (ETP) is more conductive but more prone to hydrogen embrittlement.
Can the pancake coil be supplied in custom diameters? Yes, we offer outer diameters from 3/8” to 5/8” (or metric equivalents) and wall thicknesses from 0.6mm to 1.5mm. Custom lengths are also available upon request.
Is the tube suitable for use with R32 or R410A refrigerants? Absolutely. Our C12200 seamless copper tube is compatible with all common refrigerants including R32, R410A, and R134a, as long as the system design meets pressure requirements.
How do you prevent internal oxidation during manufacturing? We use a controlled annealing atmosphere and clean the tubes with high-pressure nitrogen to ensure a bright, oxide-free inner surface.
What is the typical lead time for an order? For standard sizes and quantities, lead time is approximately 15–25 days after deposit. Custom orders may require 25–35 days.
Do you provide samples for testing? Yes, we can provide free samples for pre-qualification, though the buyer pays for shipping. Contact our sales team for details.
What certifications do your products carry? Our manufacturing processes are certified under ISO9001, ISO14001, OHSAS18001, and others. Each batch can be supplied with a mill test certificate (MTC) as per EN 10204 3.1.
Can the coil be used in outdoor air conditioning units without extra coating? The standard coil has good natural corrosion resistance. For outdoor installation in coastal or industrial areas, we recommend requesting an additional anti-corrosion coating (optional).
